Php PayPal IPN已停止工作

下面的脚本运行了好几个小时，突然停止了工作

我没有改变任何事情

下面是否有任何看起来不正确的东西会妨碍它正常工作

<?php

// STEP 1: read POST data

// Reading POSTed data directly from $_POST causes serialization issues with array data in the POST.
// Instead, read raw POST data from the input stream.
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
    $keyval = explode ('=', $keyval);
    if (count($keyval) == 2)
        $myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
    $get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
    if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
        $value = urlencode(stripslashes($value));
    } else {
        $value = urlencode($value);
    }
    $req .= "&$key=$value";
}


// Step 2: POST IPN data back to PayPal to validate

检查您的PayPal帐户中的IPN历史记录，查看IPN是否实际被发送，以及返回的响应。如果它显示它们正在被发送，并且包含200个响应，那么这意味着您的脚本正在被命中并成功完成。在这种情况下，您需要检查脚本的逻辑，看看为什么它没有按照您的想法执行

如果它根本不发送，您需要仔细检查PayPal帐户中的IPN配置或付款请求中使用的通知URL

如果它显示它正在发送但得到的响应不是200，则意味着您的IPN脚本失败。您可以查看web服务器日志，了解错误的具体内容并解决问题。
请参阅

它似乎在发送无关的数据

我记录了paypal对验证的响应，它会在我记录的重要位置周围发送一些信息

您是否收到任何错误消息？你有网络或mysql访问权限吗？没有错误，托管和mysql工作得很好！我检查了我的IPN历史记录，一切都很好，ai有Http 200响应和IPN消息OK，然后正如我提到的，这意味着脚本被PayPal的服务器命中，它返回一个响应，说它成功完成了。如果在运行的脚本中看不到应该发生的事情，则需要仔细检查逻辑。
